My friend is in USA on J1 visa and needs a "No Ojection Letter" from Nepal for the J visa waiver in order to change the visa and file for green card this year.

What is the step by step procedure for this?

Who has to have this letter for the waiver?

From where in Nepal can it be obtained?

Any form of sample letter?

Please share your experience in this thred. I am sure there are many our here in the similar situation.

Thanks!
